Description

{FIRE SUPPRESSION SYSTEM FOR ELECTRIC VEHICLE}

The present invention relates to an electric vehicle fire suppression system, and more specifically, to an electric vehicle fire suppression system configured to quickly extinguish an electric vehicle fire.

As interest in environmentally friendly electric vehicles grows over internal combustion engine vehicles that emit greenhouse gases, the government has announced a policy to supply 3.62 million electric vehicles by 2030, showing that the automobile market trend is rapidly changing from internal combustion engine vehicles to electric vehicles.

However, electric vehicle fires can cause high-temperature flames to occur in an instant due to thermal runaway of lithium-ion batteries, so extinguishing them requires more time, manpower, and money than fires in general internal combustion engine vehicles.

Currently, there are many problems with extinguishing electric vehicle fires, such as the fact that it is difficult for an individual to respond quickly on their own, the fact that it takes a long time to install fire extinguishing equipment, making initial response impossible, and the fact that in the case of a fire in an indoor parking lot, it is difficult to enter the fire site, making initial response difficult.

In this regard, Korean Patent Publication No. 2022-0162197 (hereinafter referred to as “prior document”) discloses a fire suppression gun for suppressing electric vehicle fires.

The fire suppression gun of the prior art is characterized by including a flat fire suppression gun covering an electric vehicle, a backflow prevention exhaust adapter connected to at least one air damper provided in the fire suppression gun and allowing air to move only in the exhaust direction, and an exhaust device connected to the backflow prevention exhaust adapter and operating an exhaust fan by measuring the concentration in the air being moved.

The fire suppression blanket of the prior literature has the advantage of improving the convenience of fire suppression by covering an electric vehicle with the fire suppression blanket to block the internal and external air, thereby suffocating the internal air and suppressing and suppressing the spread of fire, and selectively discharging toxic gases.

However, the fire suppression gun in the prior literature has the problem that it is difficult to properly cover the electric vehicle due to the high-temperature flames and there is a high possibility of injury because a person must find the fire suppression gun, carry it, move to the electric vehicle where high-temperature flames have occurred in an instant due to the thermal runaway phenomenon of the battery, and cover the electric vehicle with the fire suppression gun.

Therefore, in the event of a fire in a parked electric vehicle, a method is required that enables rapid initial response and complete extinguishment of the electric vehicle fire, and minimizes human and material damage by blocking the spread of fire and harmful gases to surrounding vehicles until firefighters arrive.

Republic of Korea Patent Publication No. 2022-0162197 (Publication Date: 2022.12.08)

As shown in FIGS. 1 to 4, the tent part (100) includes a first frame (110), a first fire extinguishing cloth (120), and a first water barrier (130).

The first frame (110) forms the skeleton of the tent section (100). The first frame (110) is composed of a plurality of pipes. The plurality of pipes are positioned at the corners of a solid figure. Here, the solid figure may mean a rectangular solid.

A plurality of pipes are joined together by bolting, welding, etc. at the points where the corners meet. The plurality of pipes can be provided in the form of circular pipes, etc.

The first frame (110) is installed in a part of a parking area (1). Here, the parking area (1) means a parking line painted on the ground. Here, the parking area (1) means a rectangular parking line where one electric vehicle can be parked.

Here, the parking area (1) may be a parking area (1) equipped with an electric vehicle charging device. Among the first frames (110), the pipes that are placed on the floor may be placed above a portion of the parking line.

The first fire extinguishing cover (120) covers the first frame (110) in a form that forms an opening (101) on the front. Here, the opening (101) forms an entrance through which a vehicle (2) such as an electric vehicle enters. The first fire extinguishing cover (120) forms a surface of the three-dimensional shape described above, excluding the opening (101) and the bottom surface.

The edge of the first fire extinguishing cloth (120) can be wrapped around the pipe of the first frame (110) and then kept in a state of covering the first frame (110) by a snap button, Velcro, etc. The first fire extinguishing cloth (120) is provided as a suffocating fire extinguishing cloth.

As shown in Fig. 2, a zipper (121) is provided on one side of the first fire extinguisher (120). If the fire sensor (510) malfunctions and a person is trapped in the isolation space (S), the person can escape to the outside through the emergency exit created by opening the zipper (121).

The first order wall (130) is joined to the lower part of the first frame (110). That is, the first order wall (130) is joined to pipes that are seated on the bottom of the first frame (110).

The lower part of the first water barrier (130) is in close contact with the floor surface. A member such as rubber that is elastically deformable and can be in close contact with the floor surface can be combined at the lower part of the first water barrier (130). Accordingly, the gap between the tent part (100) and the floor surface is eliminated. Accordingly, the movement of fluid through the gap between the tent part (100) and the floor surface is blocked.

As shown in FIGS. 1 to 4, the door part (200) includes a second frame (210), a second fire extinguishing film (220), and a second water barrier (230).

The second frame (210) forms the skeleton of the door part (200). The second frame (210) is composed of a plurality of pipes. The plurality of pipes are located on the side of the face corresponding to the opening (101). Here, the face corresponding to the opening (101) may mean a square.

A plurality of pipes are joined together by means of bolting, welding, etc. at the point where the pipes meet. The plurality of pipes can be provided in the form of circular pipes, etc.

The second frame (210) is rotatably coupled to the first frame (110) at the bottom of the opening (101). 211 in FIGS. 3 and 4 denotes a hinge axis (211) of the second frame (210) rotatably coupled to the first frame (110). The second frame (210) can be rotated to be adjacent to the opening (101) (see FIGS. 1 and 3).

Since the hinge axis (211) of the second frame (210) is located at the lower part of the opening (101), the second frame (210) can be rotated to be settled on the remaining part of the parking area (1) (see FIGS. 2 and 4). Here, the remaining part of the parking area (1) means a parking line other than the parking line on which the first frame (110) is settled. The second frame (210) can be settled on the parking line.

A fire sensor (510) is installed on one side of the tent part (100). As shown in FIG. 1 and FIG. 2, the fire sensor (510) may be installed on the upper side of the tent part (100). The fire sensor (510) includes at least one of a flame detection sensor, a temperature sensor, and a gas detection sensor.

The door part (200) can be rotated in both directions by the driving part (300). The driving part (300) includes a servo motor (310). The rotation axis of the servo motor (310) transmits rotational force to the hinge axis (211) of the second frame (210).

When the fire sensor (510) detects a fire in the parking area (1), the driving unit (300) rotates the door unit (200) by 90 degrees to close the opening (101) (see FIGS. 2 and 4). After the electric vehicle fire is extinguished, the driving unit (300) rotates the door unit (200) by 90 degrees to open the opening (101) (see FIGS. 1 and 3).

The second fire extinguishing cloth (220) connects the tent section (100) and the second frame (210). Accordingly, when the second frame (210) is rotated to be settled in the remaining part of the parking area (1) (see FIGS. 2 and 4), the second fire extinguishing cloth (220) is spread tautly and the door section (200) can close the opening (101).

When the second frame (210) is rotated so that it is adjacent to the opening (101) (see FIGS. 1 and 3), the second fire extinguisher (220) can be folded in a winding manner between the opening (101) and the second frame (210) to open the opening (101).

The edge of the second fire extinguisher (220) can be wrapped around the pipe of the second frame (210) and then secured with a snap button, Velcro, etc. The second fire extinguisher (220) is provided as a suffocating fire extinguisher.

The second retaining wall (230) is connected to the second frame (210). Accordingly, when the second frame (210) is rotated to be settled in the remaining part of the parking area (1) (see FIGS. 2 and 4), the lower end of the second retaining wall (230) is in close contact with the floor surface.

A material such as rubber that is elastically deformable and can adhere to the floor surface can be combined at the bottom of the second wall (230). Accordingly, when the second frame (210) is rotated to be settled on the remaining part of the parking area (1) (see FIGS. 2 and 4), the gap between the door part (200) and the floor surface is eliminated. Accordingly, movement of fluid through the gap between the door part (200) and the floor surface is blocked.

As shown in FIG. 2 and FIG. 4, when the opening (101) is closed, the tent part (100) and the door part (200) cover the entire parking area (1), confining the vehicle (2), such as an electric vehicle, in an isolated space (S).

Accordingly, when the fire sensor (510) detects a fire within the parking area (1), extinguishment by smothering, which blocks the supply of air (oxygen) by blocking the inflow of outside air into the isolation space (S), can be possible. In addition, water leakage supplied to the isolation space (S) through the water supply device (610) and the free water supply device (700) can be blocked.

As shown in FIGS. 3 and 4, a pair of draw rails (140) are coupled to the upper portion of the first frame (110). The pair of draw rails (140) are coupled to the upper left and right sides of the opening (101). The pair of draw rails (140) form a long pipe shape that opens toward the opening (101).

The door part (200) includes a pair of multi-stage rail frames (240). The multi-stage rail frame (240) forms a multi-stage rail shape that slides in multiple stages. One end of the multi-stage rail frame (240) is slidably connected to a draw-out rail (140). The other end of the multi-stage rail frame (240) is connected to a second frame (210).

As shown in Fig. 4, the multi-stage rail frame (240) includes a first rail frame (241), a second rail frame (242), and a third rail frame (243).

The first rail frame (241) is slidably connected to the inside of the withdrawal rail (140). The second rail frame (242) is slidably connected to the inside of the first rail frame (241). The third rail frame (243) is slidably connected to the inside of the second rail frame (242). The end of the third rail frame (243) is connected to the second rail frame (242).

With the opening (101) open (see FIGS. 1 and 3), the second frame (210) is adjacent to the opening (101). Accordingly, the multi-rail frame (240) is inserted into the withdrawal rail (140).

When the driving unit (300) rotates the door unit (200) to close the opening (101) (see FIGS. 2 and 4), the multi-stage rail frame (240) slides in multiple stages and is pulled out in multiple stages from the pull-out rail (140).

The multi-stage rail frame (240) is made of a material that is elastically flexible and deformable, like a fishing rod. Accordingly, when the driving unit (300) rotates the door unit (200) to close the opening (101) (see FIGS. 2 and 4), the multi-stage rail frame (240) is elastically flexible and deformed according to the rotation of the second frame (210), and the second fire blanket (220) is supported tautly between the tent unit (100) and the second frame (210).

The floor frame (400) is placed on the ground along the edge of the parking area (1). The floor frame (400) may form a rectangular frame shape. Some of the pipes placed on the ground among the first frame (110) may be placed on the upper surface of the floor frame (400).

A material such as rubber that is elastically deformable and can adhere to the floor surface (ground) can be combined at the bottom of the floor frame (400). Accordingly, the gap between the floor frame (400) and the ground is eliminated. Accordingly, movement of fluid through the gap between the floor frame (400) and the ground is blocked.

The floor frame (400) is composed of a plurality of pipes. The plurality of pipes are joined to each other by means of bolting, welding, etc. at the points where the sides meet. The plurality of pipes may be provided as square pipes, etc.

The first order wall (130) is in close contact with the floor frame (400). The first order wall (130) includes a first protrusion (131). The first protrusion (131) protrudes from the inner surface of the first order wall (130) toward the isolation space (S). Here, the inner surface means a surface of the first order wall (130) facing the isolation space (S).

The first protrusion (131) is secured to the upper surface of the floor frame (400). A member such as rubber that is elastically deformable and can be in close contact with the upper surface of the floor frame (400) can be joined to the lower portion of the first protrusion (131). Accordingly, the gap between the first water barrier (130) and the floor frame (400) is eliminated. Accordingly, movement of fluid through the gap between the first water barrier (130) and the floor frame (400) is blocked.

In a state where the second frame (210) is rotated to be settled in the remaining part of the parking area (1) (see FIGS. 2 and 4), the second water barrier (230) is in close contact with the floor frame (400).

The second order wall (230) includes a second protrusion (231). The second protrusion (231) protrudes from the inner surface of the second order wall (230) toward the isolation space (S). Here, the inner surface means a surface of the second order wall (230) that faces the isolation space (S).

The second protrusion (231) is secured to the upper surface of the floor frame (400). A member such as rubber that is elastically deformable and can be in close contact with the upper surface of the floor frame (400) can be joined to the lower portion of the second protrusion (231). Accordingly, the gap between the second water barrier (230) and the floor frame (400) is eliminated. Accordingly, the movement of fluid through the gap between the second water barrier (230) and the floor frame (400) is blocked.

When the opening (101) is closed, the first water barrier (130) and the second water barrier (230) are in close contact with the floor frame (400) along the edge of the parking area (1). When the opening (101) is closed, the tent part (100) and the door part (200) cover the entire parking area (1), confining the vehicle (2), such as an electric vehicle, in an isolated space (S).

Accordingly, when the fire sensor (510) detects a fire within the parking area (1), extinguishment by smothering, which blocks the supply of air (oxygen) by blocking the inflow of outside air into the isolation space (S), can be possible. In addition, water leakage supplied to the isolation space (S) through the water supply device (610) and the free water supply device (700) can be blocked.

As shown in Fig. 4, the free water supply device (700) is a device capable of free water supply to an isolated space (S). When the fire sensor (510) detects a fire in the parking area (1), the free water supply device (700) free water supplies water from the upper side of the isolated space (S).

The free-flowing water device (700) includes an inlet pipe (710) and a sprinkler (720). The inlet pipe (710) is connected to a water pipe or an indoor fire extinguisher. The inlet pipe (710) is connected to the upper side of the tent section (100).

An electronic valve is provided in the inlet pipe (710). When the fire sensor (510) detects a fire in the parking area (1), the electronic valve opens and free water supply through the sprinkler (720) is initiated. Therefore, a quick initial response to an electric vehicle fire can be made.

As shown in Fig. 4, the water supply device (610) is a device that injects water into the isolation space (S). When the fire sensor (510) detects a fire in the parking area (1), the water supply device (610) injects water into the isolation space (S).

The water supply device (610) includes a water supply pipe (611). The water supply pipe (611) is connected to a water pipe or an indoor fire extinguisher. The water supply pipe (611) is connected to one side of the tent section (100).

An electronic valve is provided in the water supply pipe (611). When the fire sensor (510) detects a fire in the parking area (1), the electronic valve opens and the water supply pipe (611) starts to supply water. The water level in the isolation space (S) rises by the water supply device (610), and the electric vehicle in which a fire has occurred is completely submerged in water. The water level in the isolation space (S) is maintained until the electric vehicle fire is completely extinguished. Therefore, the electric vehicle fire can be effectively extinguished.

The smoke exhaust device (800) is a device that exhausts toxic gas from the isolation space (S). As shown in Fig. 4, when the fire sensor (510) detects a fire in the parking area (1), the smoke exhaust device (800) exhausts toxic gas from the upper side of the isolation space (S).

The smoke exhaust device (800) includes a smoke exhaust duct (810) and a fan. The smoke exhaust duct (810) is connected to the upper side of the tent part (100). When the fire sensor (510) detects a fire in the parking area (1), the fan operates to start exhausting toxic gas through the smoke exhaust duct (810). The exit of the smoke exhaust duct (810) is provided on the outside of the building where the parking area (1) is located. Therefore, damage caused by toxic gas generated from a burning vehicle can be prevented.

The water level sensor (520) detects the water level of the isolation space (S). The water level sensor (520) may be equipped with an ultrasonic sensor. As shown in FIGS. 1 and 2, the water level sensor (520) may be installed on the upper side of the tent section (100).

The drainage device (620) includes a drainage pipe (621) and a drainage pump. The drainage pipe (621) is connected to one side of the tent section (100).

An electronic valve is provided in the drain pipe (621). When the water level sensor (520) detects the set water level, the electronic valve opens and drainage through the drain pipe (621) begins.

The drain pump controls the amount of water drained through the drain pipe (621) so that the water level in the isolation space (S) is maintained at the set level. Accordingly, the set water level in the isolation space (S) is maintained until the electric vehicle fire is completely extinguished. Accordingly, the electric vehicle fire can be effectively extinguished.

As shown in Fig. 4, the drain (630) is a pipe that completely drains the water in the isolation space (S). The drain (630) is connected to the lower side of the tent part (100). An on-off valve is provided in the drain (630). When an electric vehicle fire is completely extinguished, the parking area (1) staff or firefighters can open the on-off valve to completely drain the water in the isolation space (S).

As shown in FIGS. 1 and 2, the display device (900) is installed outside the isolation space (S).
